Solidworks CAM Lathe:
I'm trying to use a boring bar to enlarge the diameter of a blind hole, however the operation insists on continuing in the X direction at the bottom of the hole toward the part center line (flat bottom hole initially drilled with a custom drill to create the flat bottom), and as the boring bar has a diameter larger than half of the hole its creating it collides with the back side of the hole.
Is there a way to have the ID feature only select the portion of the hole feature in the Z direction? (every video or example I can find online has a through hole and not a blind one).
There's two things that can cause issues here:
1. The feature needs to be properly defined. Make sure you have just the wall selected and not the bottom of the hole. As long as your leads don't extend the toolpath, you should be able to turn just the wall section of the hole. See the red line below.
2. You may have to set Leftover WIP to NONE in the Bore Finish tab of the Operation Parameters dialogue. If it sees extra stock it may try to add toolpaths to remove it.
If you want to clean some of the floor close the wall(with the feature defining the bottom of the hole as well), try adjusting your start/end length in the Feature Options tab of the Operation Parameters. If this does not work, you may need to create a feature based off of a sketch that you define.
